Recently, we have seen a national stadium for fitness, which is representative. The sports lighting system is simple:
Lamp post: 4
Cloth lamp mode: the multi-pole placement on both sides.
Number of lights: 5 sets/poles.
Total number of lights: 20 sets
There are tens of thousands of similar sports venues, including schools and community sports venues.
In our country, there is a large gap between this and developed countries, which also indicates that we still have great development space and potential.
Figure 1 lighting site
This arrangement is very suitable for the stadium without TV broadcast, which can meet the needs of amateur competition, training and national fitness.
The lighting fixtures on both sides have better economical efficiency and can meet the basic lighting requirements.
Usually, the lamp posts are arranged on the two sides of the field. Generally speaking, the height of the light pole of the multi-pole cloth lamp can be lower than that of the four corners, which is the main reason of economy.
Bar decorate more often have four bar decorate, shown in figure 2 "4", also has six pole placement, as shown in figure 2 of the "low", I have eight pole arrangement, "end" is shown in figure 2, there is almost no use light pole pole arrangement or ten rod above arrangement.
Unless the expansion project, also seldom USES odd lamp pole arrangement way.
Figure 2 multi-bar arrangement of lamps.
In order to avoid glare interference of a goalkeeper and attacking players, with the goal line midpoint as the benchmark, at least within 10 ° Angle on both sides of the bottom line is best not to decorate a light pole, pink areas in the figure.
FIFA gives the minimum height of the lamp pole, that is, the height of the lamp must be equal to h greater than 15m.
Even at the same time meet the requirements of phi acuity 25 ° in figure 3.
FIG. 3 installation height triangle of lamps.
In figure 3, h is the installation height of the luminaire;
D is the distance from the base of the lamp to the center line of the long axis of the site;
See the Angle in figure 3.
It can be seen from this that, even if the national stadium lighting court, sports lighting is more complex.
Unfortunately, there are still not owner did not attach enough importance to sports lighting, optional put a few lights to meet the requirements of the light, the effect of the cause of any lighting stadium, affect the development of nationwide fitness campaign.
Because it's simple, so the economy;
It's easy to generalize because of the economy.
The sports lighting of national fitness has bigger development space!
